Sure
And how long does it take for silver to visibly tarnish if left exposed to
the air?
Months
How long would it take for enough environmental Sulphur to dissolve into a
capped jug of distilled water to make any difference?
Uh...won't happen, it's capped.
Uncapped, try a few years.

1. As I described, sulfur is everywhere. if you own a car, you burn
gasoline. That releases a great deal of sulfur into the air. If you
have a car, you are near a road. Other cars drive on that road,and
they release sulfur into the atmosphere. You will experience tarnish
on your silver electrodes. It is unavoidable.
2. As I described, you probably find your kitchen sink smells from
time to time. This releases sulfur into the air. I recommend to
clean it often.
3. If you have a car, you have a lead-acid battery. The acid is
sulfuric acid. This releases sulfur into the home. If you place your
nose near the battery and sniff - that's what sulfur smells like.
4. Sulfur tarnishes silver readily. It is inescapable and
unavoidable. It can severely disrupt the brewing process, and cause
a significant reduction in the conductance of the solution in the
first 48 hours after the brew.
5. Silver sulfide is yellow, not black. See
"http://upload.wikimedia.org/wikipedia/commons/thumb/d/d6/StirlingSilverForks.jpg/252px-StirlingSilverForks.jpg";
6. Silver sulfide is not an oxide. I gave the equation in my post:
2Ag + H2S --> Ag2S + H2(g)
7. Reversing the polarity does not eliminate the sulfur. It merely
moves it from the cathode to the anode, and leaves some in the
solution. This is what disrupts the brewing process and reduces the
conductance after the brew is finished.
8. Performing the desulfurizing process I described reduces the
conductance loss from 40%to 60% down to less than 12%.
9. Wiping the electrodes has no effect on the tarnish, and does not
affect the drop in conductance.
10. Wiping the electrodes is a very bad habit and contributes to
further contamination from the tissue and from your fingers.
For example, if you look at the electrodes very carefully in the
right angle, you will see fragments of the tissue stuck to the
electrodes. This contains chemicals from the paper process, that
contaminate the dw. So wiping contributes to the loss in silver ion
concentration.
11. Since the SilverCell process does not produce any silver
hydroxide, there is no need to wipe the electrodes. You no longer
suffer the loss in silver ion concentration due to contamination.
The myths, misunderstandings and miscomprehension of the silver
process have severely diminished the capability of this wonderful
metal.
I have, by a simple change to the process, increased the silver ion
concentration by about a factor of ten, from less than 5% to over
44%.
I have shown how to reduce the drop in conductance due to sulfur
contamination from 40% to 60% to less than 12%.
I have shown how to eliminate the leaching of plain glass containers
by changing to borosilicate. These are readily available all over
the world, and are called beakers. They are very inexpensive.
These are very significant improvements.
This is from studying the process carefully, and finding out how it
actually works. Then by finding what it needs to improve the entire
process, and by continually reviewing the results and improving them
again.
You can see the results on my forum at

These advantages are not available anywhere else on the web.
I will post a copy of these discussion to my forum.
